The map would have been good if it weren't for that mountain priest or whatever he is, and the mine. It's impossible to find without a description. But the main thing that ruined it, after several hours of playing, I killed Nicholas, but he still controlled two castles, and as a result, they became allied, and the quest remained unfinished. Great! I have to start all over again...

I played as a Warrior and got the Vampire badge. I just ignored the quests (Nicholas, the dungeon, and the artifacts). The arena isn't quite clear with this boss. I didn't have enough strength to defeat him, so I reloaded. Why is he even there? This time, I built the Ash's Tear.
